SX EW Capital & Operating Cost of Solvent Extraction ...

The diluent used in copper SX typically has a high flash point and thus copper SX plants could be classified as non-hazardous areas. From a general survey by Miller (5), over 50% of copper SX plants were found to be unclassified or unrated for electrical apparatus fire initiation. Many of the advances made in the understanding

AN INDUSTRIAL COPPER SOLVENT EXTRACTION PROCESS

process. Since the copper solvent extraction process has similar characteristics to those processes in which model predictive control has been successfully applied, the first aim is to develop dynamical process models. A phenomenological steady state simulation model for a copper SX/EW pilot plant has been developed by Aminian et al. (2000).
